Average response profiles of 4 major clusters in rhesus CT fibers. The stimuli are listed along the X-axis, whereas the average impulse activity measured over 5 s is plotted along the Y-axis. Error bars indicate SE. Hatched columns: salts. Dark gray columns: umami compounds. Open columns: acids. Light gray columns: bitter compounds. Black columns: sweeteners. It is interesting that the cluster analsis added an H-clusters to the 3 other. [46]
